Seamless Satellite Switching

The high-traffic regions of the global mini-VSAT Broadband coverage
area are covered by more than one satellite. The ICM's built-in modem
maintains a list of all satellites in the network and, with input from the
Hub, selects the highest priority satellite that provides coverage at the
vessel's current GPS location. If the antenna is unable to track the
chosen satellite for any reason (due to a blockage condition, for
example), the modem selects the next available satellite on the list and
the antenna automatically switches to that satellite.
In addition, whenever the vessel travels outside the boundary of the
current satellite's coverage area, with input from the Hub, the modem
selects the highest priority satellite in the adjoining region and the
antenna automatically switches to that satellite to maintain the service
connection.
